We almost missed these. Can you update your scripts to auto-cc folks on the Reported-by line, and optionally include the lists where the report originated next time? This is looking good from my tests, you can add: Tested-by: Dan Williams <dan.j.williams@xxxxxxxxx> ...but I still want to take a look at some of the implementation choices.
